CHLOEOSCIKTUS.— SCUDDERIA. 327 



1. Chloroscirtus forceps, sp. n. (Tab. XV. figg. 24-27.) 



Totus viridis, immaculatus. Caput, angustum. Oculi globosi, vel horizontaliter subovati. Frons utrinque infra 

 oculos breviter impressa. Pronoti canthi rotundato-acuti, recti, flavi ; lobi laterales margine infero 

 toto rotundato, in medio altiores. Elytra longissima, angustissima, modice coriacea, nitida, densissime 

 reticulata, venisque transversis parallelis distinctis. Campus marginalia parura latius reticulatus, parum 

 translucidus, venis costalibus numerosis, apice furcatis ; vena mediastina distincta, brevis, ramosa. 

 Campus tympanalis sinister crasse punctatus, dexter reticulatus, areola trigonali diaphana. Femora 

 postica sat brevia, ultra medium elytrorum attingentia, vix dimidia parte apicali lineari. 



($ . Segmentum anale latissimum, margine deflexo. Lamina supra-analis abscondita, ad inferum deflexa, 

 perpendicularis, rotundata, in medio profunde fissa, rotundato-bilobata. Segmentum anale supra in medio 

 sulcum in forma litterse Y prsebens, margine postico sinuato, ejus angulis appendicibus brevissimis minutis 

 compressis instructis. Cerci (fig. 27) arcuati, apice oblique truncato, acuto, nigro, subtus dente apicali 

 minimo instructo, ac intus ante apicem spina fusca longissima, acutissima, perpendiculari armati. Lamina 

 infra-genitalis (fig. 26) longe forcipato-producta ; in parte basali acute carinata ; carina apice in angulo 

 forcipis dentem acutam trigonalem formante ; rami foreipis dimidiam longitudinem totae lamina? infra- 

 genitalis sequantes, compressi, arcuati, facie interna sulcata, externa late rotundato-carinata ; ramis simul 

 sumptis ellipsam apice apertam formantibus. Elytri dextri tympanum speculo trigonali, reticuloque 

 hyalinis. 



cf . Long. corp. supra 21*5 ; cum lam. subg. 24 ; pronot. 5*8 ; elytr. 36, latit. 7"5 ; femor. post. 19 millim.

When the styli are broken off, the present species might easily be confounded with 

 Scudderia forcipata (infra, p. 332), which has a very similar infra-genital plate ; but 

 the ends of the branches of the infra-genital plate appear to be finely notched, with 

 the inferior angle triangular and compressed, while in S. forcipata the ends of the 

 branches of the forceps are attenuated and rounded.

The members of this genus are spread over North and South America, most of the 

 northern forms extending into Mexico. The southern representatives are generally 

 of larger size. The males of the various species are easily separated by the form of 

 the anal plate, but most of the females are very similar to each other. The dorsal 

 field of the males is broadly reticulated, often hyaline in the cells ; in the right elytron 

 its reticulation is mostly subhyaline. The ovipositor of the female varies in its breadth 

 and curvature, though differing slightly in form according to the species.
